Description

Technical Field

[0001] The utility model relates to the field of diaphragm valves, in particular to an electric regulating diaphragm valve for a copper foil production line. Background Art

[0002] The copper foil production process requires precise flow control of various fluids, such as cooling water and chemicals. An electric regulating diaphragm valve is a valve used to control fluid flow and primarily consists of a valve body, diaphragm, and electric actuator. Its primary function is to regulate and control fluid flow, pressure, or temperature to meet the needs of various industrial processes. Therefore, an electric regulating diaphragm valve can automatically adjust flow based on production process requirements to ensure stability and consistency.

[0003] After the electric actuator of the electric regulating diaphragm valve receives the control signal from the upper control system, the electric motor inside the electric actuator rotates according to the received control signal, driving the built-in lever mechanism to convert the electrical signal into mechanical movement, causing the diaphragm to move up or down. According to the opening of the diaphragm, the flow rate of the fluid is adjusted to the set requirements.

[0004] However, after long-term use, the inside of the diaphragm valve's input pipe will be worn and damaged, which will affect the sealing effect and require replacement and maintenance. However, the disassembly and assembly of the diaphragm valve and the input pipe is rather cumbersome and requires a lot of manpower and time. Therefore, an electric adjustable diaphragm valve for a copper foil production line is proposed to solve the above problem. Utility Model Content

The supporting frame 9 is used to clamp the block 12 to fix the card column 10. The interior of the fixing frame 8 is slidably connected to the card column 10. The side wall of the card column 10 is fixedly connected to a fixing block 11. The side wall of the card column 10 is fixedly connected to the block 12. The side wall of the card column 10 is sleeved with a first spring 13. The first spring 13 is used for rebound reset. One end of the first spring 13 is fixedly connected to the interior of the fixing frame 8, and the other end of the first spring 13 is fixedly connected to the side wall of the block 12. The side wall of the block 12 is slidably connected to the interior of the support frame 9, and the side wall of the card column 10 is slidably connected to the interior of the fixing hole 7;

[0035] The first spring 13 loses the squeezing of the block 12 and rebounds to reset, and the post 10 is stuck in the fixing hole 7 again, fixing the plug rod 6.

[0036] Reference Figure 4 and Figure 5The filter assembly includes an inlet pipe 5, a filter frame 15 is provided inside the inlet pipe 5, the filter frame 15 is used to filter impurities, the side wall of the filter frame 15 is rotatably connected to a handle 16, the handle 16 is convenient for pulling out the filter frame 15, the side wall of the filter frame 15 is fixedly connected to a connecting plate 17, a connecting hole 18 is opened inside the connecting plate 17, a sleeve 19 is fixedly connected to the inside of the inlet pipe 5, a limit block 20 is fixedly connected to the inside of the sleeve 19, a slide plate 22 is slidably connected to the inside of the sleeve 19, a second spring 23 is provided inside the sleeve 19, the second spring 23 is used for rebound reset, the side wall of the slide plate 22 is fixedly connected to a connecting block 21, the connecting block 21 is slidably connected to the inside of the connecting hole 18, one end of the second spring 23 is fixedly connected to the side wall of the limit block 20, and the other end of the second spring 23 is fixedly connected to the side wall of the slide plate 22;

[0037] When installing the filter frame 15, the filter frame 15 is pushed by the handle 16 so that the connecting plate 17 is aligned with the mounting hole inside the input pipe 5 and inserted. During the movement of the connecting plate 17, it contacts the upper surface of the connecting block 21. The connecting plate 17 will squeeze the connecting block 21, forcing the connecting block 21 to move downward and push it into the sleeve 19, so that the second spring 23 is squeezed and deformed. As the connecting plate 17 continues to move, the connecting block 21 will be completely squeezed into the sleeve 19. When the connecting hole 18 opened in the connecting plate 17 moves to a position exactly aligned with the connecting block 21, the second spring 23 will reset due to the loss of pressure, and the connecting block 21 will be pushed into the connecting hole 18 by the reset force of the second spring 23, thereby fixing the filter frame 15.

[0038] Working principle: The diaphragm valve needs to be replaced and repaired after long-term use. The fixing block 11 is used to move the clamping column 10, and the clamping block 12 squeezes the first spring 13 to shrink it. When the clamping column 10 is out of the fixing hole 7, the fixing block 11 is rotated to make the clamping block 12 stuck in the support frame 9 to prevent the clamping column 10 from moving. Then the insertion rod 6 is pulled out to separate the connecting plate 4 from the valve body 3, so that the input pipe 5 and the valve body 3 can be replaced and maintained. After the maintenance is completed, the valve body 3 is aligned with the connecting plate 4, and the insertion rod 6 is inserted into it. The clamping column 10 is rotated to move the clamping block 12, and the fixation of the clamping column 10 is cancelled. The first spring 13 rebounds and resets, and the clamping column 10 is stuck in the fixing hole 7 to fix the insertion rod 6.

[0039] When installing the filter frame 15, align the connecting plate 17 with the inside of the input pipe 5 and insert it. During the movement, the connecting plate 17 will squeeze the connecting block 21 and push it into the inside of the sleeve 19, so that the second spring 23 is squeezed and deformed. When the connecting hole 18 opened in the connecting plate 17 moves to the bottom of the connecting block 21, the second spring 23 will reset due to the loss of pressure and push the connecting block 21 downward, locking it into the inside of the connecting hole 18, thereby fixing the filter frame 15.
